Why would you put bondo on top of the original red paint?
(inner wheel tubs)
In most cases you would want the entire car strip properly before any rust repair is started in my opinion....

Are the areas behind the new 1/4 panel getting any kind of attention?

The B7 Cuda will be well under the $25K max as you said, where will this Bee fall? Still $25K max?

I don't quite understand how installing the new AMD full 1/4 would be the same price (time)as installing/blocking these partial 1/4's
